I searched first before I posted this, and may have overlooked a previous post with the same question (so, apologies in advance, if warranted).

Here's my problem-I have an 8700G, which had banged up housing, so I replaced it. Upon restarting the device after completion, I noticed that I cannot hear any outbound or inbound voice calls, including speakerphone. The only way I can continue to use the device is to use my Bluetooth headset, and my calls go on without a hitch. Everything else works just fine, such as web-browsing and sending and receiving emails.

I simply think it's ironic that only after I replace the housing do I have this issue, and I'm cautious of opening it up again, only to get no better results, although I'd do about anything at this point.
